Background

SAMe is made in the body from a reaction between methionine, which is an essential amino acid, and adenosine triphosphate, a molecule that carries energy. SAMe is involved in many different reactions in the body.

SAMe has been used to treat psychiatric illnesses, infertility, liver problems, premenstrual disorders, and musculoskeletal conditions.

SAMe has been widely studied for osteoarthritis and depression. There is evidence that SAMe may help reduce the pain of osteoarthritis.

Some evidence is available for the use of SAMe for depression, fibromyalgia, and bile flow problems during pregnancy. SAMe has also been studied for its potential anti-inflammatory and pain-relieving effects. However, higher-quality studies are needed before conclusions can be made.
